According to the Adobe help in order to optimize a RSL you need to do the following:
- Create an RSL by compiling a library project in Flash Builder or building a SWC file with the compc command line tool.
- Compile your main application and reference the RSL.
- Extract the library.swf file from your RSL’s SWC file, if you haven’t done so already.
- Run the optimizer against the library.swf file
- Run the digest tool against the optimized library.swf file
- Deploy the optimized library with the application so that the application uses it at run time.
But I don't understand at what stage does the application store the new digest that was generated at stage 5?
